Research has shown that in certain periods of the year, periodic oxygen shortages can occur in marine facilities. Such conditions usually occur in late summer and early autumn when the water temperature is high and there are many fish in the cages. Oxygen deficiency is most common in the dark part of the day. Temporary lack of oxygen in the cages can also occur in other parts of the year. At unfavorable oxygen levels in the sea, an increase of only 5–10% dissolved oxygen can result in more than 10% improved growth. Adding oxygen periodically will therefore be profitable and ensure good fish welfare.
Both the Oxygenkulen and NetOx are very easy to use. The sphere can easily be lifted into place with, for example, a crane or lowered from a buoy, with only a hose for oxygen-enriched seawater going down to the sphere. NetOx Net is a hose-based diffuser that can be connected according to the design of the cages. The system is equipped with high-quality threaded connections in acid-resistant AISI 316 and can be equipped with solder in acid-resistant steel. NetOx Net is robust and designed for rough conditions.
